Introduction to Coupling Sleeve
It is the part connecting shank and rod, rod and rod. The processing of thread affects the losses of power. Coupling is used for connecting shank adapter and extension drill rod together, or for connecting two extension rods together. Besides normal equal couplings, we also offer reducing couplings that are able for changing thread type and size. The couplings we offer can be applied for our top hammer drilling system, suitable for drilling duties in tunneling, construction, mining, quarrying, etc.
